One example of an "alternate form" I can immediately think of would be something like how after The Last Jedi you know how often I saw people shitting on Rian Johnson and accusing anyone who liked Knives Out (his 2019 mystery thriller that has nothing to do with Star Wars) of being "paid off" or some shit by Star Wars fans? Or how before the release of Hellblade you had Devil May Cry fans who said they'd never forgive Ninja Theory for DmC? And to use a political example, I still recall how the Dixie Chicks said they didn't like George W. Bush and conservative country fans said they were gonna boycott their music for not being supportive of a Republican president, so it's certainly not just "woke SJWs" who are likely to want to cancel someone over a "political" matter.
Like I'm just curious really, is "cancel culture" only restricted to incidents like Jenna Marbles indefinitely leaving YouTube because of some people on Twitter shitting over a video where she had a fake tan and pretended to be Nicki Minaj back in 2011? Or would you say "cancel culture" also extends to people who say things like "I hate The Last Jedi so much that I will never see anything Rian Johnson ever makes and anyone who says Knives Out is good is a fucking paid shill"?
